Ls Electric 627059063 Mcb 30A 2-pole 480Y/277V Din Rail

Product Description

The LS ELECTRIC 627059063 is a 2-pole miniature circuit breaker (MCB) from the BK Series, rated for 30 amps at 480Y/277 VAC with a 6 kA interrupt rating. It uses a thermal magnetic trip mechanism to provide both overload and short-circuit protection. The BK63H frame houses the unit in a compact, DIN rail-mountable package suitable for panelboard and control panel installations. This breaker is installed by licensed electricians working on commercial and light industrial distribution systems where reliable branch-circuit protection is required.

This MCB is designed for use in 480Y/277 VAC three-phase commercial power distribution systems as a 2-pole branch-circuit protective device. It mounts on standard DIN rail, making it compatible with modular enclosure builds and retrofit panel upgrades. The C-curve trip characteristic suits resistive and moderate inductive loads. The IP20 enclosure rating provides basic finger protection in indoor panel environments. Wire termination is via lug and screw terminal, accepting 14 to 4 AWG conductors.

Key Features

• 2-pole thermal magnetic trip for combined overload and short-circuit protection
• C-curve trip characteristic suited to resistive and moderate inductive loads
• Standard DIN rail mounting for modular panel installation
• Lug and screw terminal accepts 14 to 4 AWG wire
• IP20 enclosure rating for indoor panel use

Compatibility

Designed as an OEM-style replacement or new-installation miniature circuit breaker for DIN rail-mounted panelboards and control enclosures in 480Y/277 VAC commercial and light industrial distribution systems.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize and lock out the panel before mounting or wiring the breaker. Verify that conductor sizing and torque values comply with NEC Article 240 and the panel manufacturer requirements. Do not exceed the 14 to 4 AWG wire size range accepted by the screw lug terminals.
