Slim Line Power & Lighting Transformer with RCD & MCB Protection

Slim Line Site Power and Lighting Transformer, 7.5kVA three-phase, developed for locations where space on site is at a premium. Manufactured in accordance with the requirements of BS4363.

Enclosure
Robust, compact, free-standing, non-vented enclosure of welded sheet steel construction, incorporating certified lifting handles. The enclosure provides protection to IP44 and has a durable, oven dried polyester powder coated finish, shade Traffic Yellow.

Rating
7.5 kVA three-phase, continuously rated

Primary Volts
400 delta connection

Primary Protection
10A TP Type “D” MCB

Secondary Volts
110NE providing a Reduced Low Voltage (RLV) supply

Distribution
1 no. 63A 4P 110V 300mA* Type A RCCB feeding: 4 no. 16A DP Type “C” MCBs each feeding a 16A 2P+E 110V IP44 socket; and 2 no. 32A DP Type “C” MCBs each feeding a 32A 2P+E 110V IP44 socket.
Also fitted with 2 no. 10A DP 110V RCBOs providing C curve MCB protection and Type A RCD protection, each feeding a 3 way terminal block for direct connection to lighting circuits (the lighting connections can be made without removing the transformer lid). The incorporation of RCD protection ensures compliance with disconnection times on longer lighting circuits with a high Zs.
*In early 2024 we will start fitting RCCBs with a 100mA sensitivity instead of a 300mA sensitivity. During the transition period you may receive a transformer fitted with an RCCB of either sensitivity.
