The Mitsubishi TCL-05SV2 is a large terminal cover specifically designed for Mitsubishi Electric's WS-V series moulded case circuit breakers in the 30A-63A frame size range for 2-pole configurations. Each package includes two covers and two sealing plates, providing complete terminal protection for both poles of a single breaker.

Exposed circuit breaker terminals present significant electrical hazards in distribution panels and control cabinets. The TCL-05SV2 eliminates this risk by providing a fitted plastic enclosure over the terminal area, protecting personnel from accidental contact with energized conductors and preventing bridging by tools or conductive debris.
Mitsubishi's snap-fit design ensures quick installation and easy maintenance access without tools or separate fasteners.
Align the cover with the breaker terminal area and press firmly until retention projections snap into engagement with pre-formed mounting holes in the circuit breaker casing.
Insert a slotted screwdriver tip into the gap at the retention projection, deflect inward to release engagement, and tilt the cover free. The tool contact point is on the plastic projection, not on live components.
The "05" in TCL-05SV2 corresponds to the 30A-63A frame range. Larger frames require different covers: TCL-1SV2 for 100A-125A frame, TCL-2SV2 for frames above 125A.
The "V2" suffix indicates 2-pole compatibility. For 3-pole breakers in the same frame size, use TCL-05SV3.
TCL indicates large terminal cover; TCS indicates small terminal cover. The small cover alternative for the same frame and pole combination is TCS-05SV2.
Both cover 2-pole WS-V series breakers in the 30A-63A frame size. TCL indicates a large terminal cover providing greater terminal area coverage for larger conductor cross-sections, while TCS indicates a smaller, narrower cover for installations with restricted space.
The TCL-05SV2 is designed for 2-pole breakers, while the TCL-05SV3 covers 3-pole configurations in the same 30A-63A frame range. A 2-pole cover will not properly fit a 3-pole breaker, leaving terminals exposed.
The TCL-05SV2 is specified for WS-V series circuit breakers. NV series earth leakage breakers within the WS-V product family and same frame size are generally compatible, but confirm against Mitsubishi's compatibility documentation before fitting.
No. The terminal cover encases only the conductor termination zone and does not contact the breaker mechanism, thermal trip element, or magnetic trip coil. The breaker's rated current, breaking capacity, and trip curve remain unchanged.
Insert a slotted screwdriver tip gently into the gap at the retention projection, deflect inward to release engagement, and tilt the cover free. Always isolate and lock-out the circuit before performing any terminal access work.
