Ls Electric 626052863 Mcb 30A 1-pole 277VAC 6ka

Product Description

The LS ELECTRIC 626052863 is a 1-pole miniature circuit breaker (MCB) rated for 30 amps at 277 VAC, designed for overcurrent and short-circuit protection in branch circuit applications. Part of the BK Series with a BK63H frame, it uses thermal magnetic trip action with a C trip curve, providing reliable protection for general-purpose loads. The interrupt rating is 6 kA, and the unit operates on 50/60 Hz systems. Terminal connections are lug-screw style, accepting 14 to 4 AWG wire. Licensed electricians and electrical contractors install this breaker in panelboards, motor control centers, and distribution enclosures where space-efficient DIN rail mounting is required.

The 626052863 is suited for residential and light commercial electrical distribution panels, industrial control cabinets, and machine control enclosures. Its IP20 enclosure rating provides basic finger protection against contact with live parts, making it appropriate for open panel and cabinet installations. The C trip curve is standard for general inductive and resistive loads, including motor feeders and lighting circuits, where moderate inrush current tolerance is needed. The operating temperature range of -5 to 40 degrees C covers most indoor service environments.

Key Features

Compatibility

Designed for use in DIN rail-mounted panelboard and control cabinet assemblies within the LS ELECTRIC BK Series, BK63H frame product family. Consult system documentation to confirm frame and bus compatibility before installation.

Installation Notes

Installation must be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize the panel and verify absence of voltage before handling or installing the breaker. Torque terminal connections per the manufacturer specification noted in the product data. Confirm wire gauge falls within the 14 to 4 AWG rated range before terminating conductors.
