With the increasing number of electrical vehicles on the road, charging stations are becoming more prevalent. While technologies have been focused on new vehicle designs and battery capacities, protection of people and the charging infrastructure also must be considered. The safety of those using the infrastructure is covered under IEC 60364-7-722 (DIN VDE 0100-722:2019-06), which requires the use of overvoltage protection in all publicly accessible charging stations. As well safety-conscious businesses and homeowners will also want to protect themselves and their investments with purpose-built surge protection. The ProBloc EV T2 V surge protectors are uniquely designed for use in AC charging systems. Raycap also offers DC surge protectors for use in DC Fast Charging infrastructure.

Overview:

• Enables V connectivity for in-line installation
• Type 2 + 3 SPD
• Discharge capacity up to 10kA (L-N) and 40kA (N-PE)
• Short circuit current rating 10 kA
• Available optional versions with or without mounting ears and remote contact

Main features & benefits:

• Ensures the most space-optimized SPD installation
• Compact design with 35mm width – suitable for even the smallest AC EV chargers
• Mounts via DIN rail installation (only 2TE width needed) or mounts flush on the backplate
• Features FastOn connection terminals. Insulated connection leads can (optional) be supplied with the SPD

The newest product in Raycap’s ZP Series, the ProTec ZPN T1H, is specifically designed for installations in buildings according to VDE 0100-443/-534 and VDE-AR-N 4100:2019-04. As with the other products in the series, the ZPN has been developed for installation onto a 40 mm busbar system. Its special features include an integrated protected output for the smart meter and the gateway and modem, and a remote monitoring contact that can be easily integrated into a smart home system. With its space saving design and innovative phase tap the ZPN can supply power for a gateway without having to expand the busbar system. The versatile ProTec ZPN fits into all types of meter cabinets and installs easily, without the need for tools or screws during installation.

An optional Terminal Bar with a simple tension clamp installation is available for use with the ZPN. An additional fuse holder for expansion cabinets is also an option. This latest ZPN product release rounds out Raycap’s 40mm busbar protection and connectivity solutions offering.

Special features ZPN:

• Thin design – fits in all cabinets between 2xSH
• Fast assembly – pluggable connection to the busbar

Special features ZP-TB:

• Large load capacity in a small installation space – high continuous current of 101A
• High safety – locking system on all busbars
• Finger safe and isolated – live parts are never touched
• Long-lasting connection – proven tension clamp enables secure connection to busbar
• Test and measure points available on all connection points

Special features ZP-FH:

• Busbar fuse holder – auxiliary power supply adapter with integrated overcurrent protection.
• An auxiliary fuse can be easily installed to protect the smart meter gateway (SMG).

ProTec T1SF Multipole Connectivity Configurations

Raycap’s ProTec T1SF Series is based on its patented Phase Gas Discharge Tube (PGDT)
technology, and a new integrated fuse technology. The products ensure safe thermal and
fault-current disconnection on networks with prospective short circuit currents as low as 300 A
and as high as 100,000 A. A coordinated thermal disconnector provides disconnection at low fault
currents (<300 A), extending a continuous fault-tripping characteristic down to 1 A.

Main features:

• Patented PGDT surge protection technology
• Integrated backup fuse
• Leakage-current free product for installation in the pre-metering area
• Shorter connecting cables – low voltage protection level
• Reduced installation space requirements, costs, wiring time and complexity
• Sensitive and reliable state-of-the-art disconnector
• Visual and remote signalization of the device status
• Short circuit current rating up to 100 kA (VDE Certified up to 75kA, 100kA additionally tested by VDE.)

Main use:

• Heavy industry installations
• Transformer stations

Benefits:

• Smallest in-class solution on the market
• Available for TN-S, TT, and TN-C networks eliminate the need for time-consuming wiring of the remote signaling contact and the cross-connection
• No problems when selecting the back-up fuse, as this is completely eliminated
• Back-up fuse and overvoltage protection are monitored and report the tripping status via the remote signaling contact

ProTec T2F Series

The practical 2-in-1 device simplifies planning, installation, and maintenance. For example, the need to dimension a backup fuse is not applicable with the ProTec T2F product series as this is already integrated and matched to its performance parameters.

The new Type 2 arrester has an integrated back-up fuse, a protection level of 1,500 V, a maximum discharge capacity of 40 kA 8/20 μs and a rated discharge current of 20 kA 8/20 μs. In addition to the proven Raycap ProTec T2 technology developed for use in systems with a rated current of up to 315 A without back-up fuse, the T2F Series with integrated backup fuse offers protection independent of installed fuses found in equipment inside large industrial installations.

Main features:

• Integrated back-up fuse
• Maximum discharge capacity of 40 kA (8/20 μs)
• Rated discharge current of 20 kA (8/20 μs)
• Complies with IEC Class II according to IEC 61643-11
• Protection level of 1,500 V
