The TCL-05SV3 offers dual-pole compatibility, making it a versatile choice for electrical panel builders. A single part number serves both 2-pole and 3-pole circuit breaker installations in the 30A-63A frame range, reducing inventory requirements.
The single-action snap-fit design allows for quick installation without tools or fasteners. This eliminates the risk of dropping hardware into live sections during fitting and enables immediate refitting if accidentally displaced during maintenance work.
Terminal covers like the TCL-05SV3 help meet operator protection and live parts enclosure requirements under standards including IEC 61439 for low-voltage switchgear and controlgear assemblies. They prevent accidental contact with live terminals during panel work and maintenance.
The TCL (large) cover provides greater depth over the terminal area compared to TCS (small) covers, accommodating larger conductor cross-sections (10 mm² to 25 mm²) typical for 30A-63A rated breakers. This ensures proper seating without interference from cable bulk.
NF Models: NF32-SV, NF63-CV/SV/HV, NF125-CVF, NF63-HDV, NF125-HDV (3-pole)
NV Models: NV32-SV, NV63-CV/SV, NV63-HV, NV125-CVF/SVF
The TCL-05SV2 is compatible with 2-pole configurations only, while the TCL-05SV3 works with both 2-pole and 3-pole breakers in the 30A-63A frame range.
No. Mitsubishi specifies that terminal covers cannot be installed on electrically operated (motorised) circuit breakers due to incompatible terminal access geometry.
As a certified Mitsubishi accessory, it contributes to meeting operator protection requirements under standards like IEC 61439 and relevant national wiring regulations.
