Ls Electric 627049763 Mcb 10A 2-pole 480Y/277VAC

Product Description

The LS ELECTRIC 627049763 is a 2-pole miniature circuit breaker (MCB) from the BK Series, rated for 10 amps at 480Y/277 VAC and built for both 50 Hz and 60 Hz systems. It uses a thermal magnetic trip mechanism to protect branch circuits against overloads and short-circuit faults. With a 10 kA interrupt rating and an IP20 enclosure rating, this breaker is suited for panel and distribution board installations in commercial and light industrial environments. Electricians working on multi-wire branch circuits or equipment branch feeds in 480-volt wye systems will find this a direct-fit panel component.

The 627049763 is designed for use in commercial and light industrial electrical distribution panels where 480Y/277 VAC branch circuit protection is required. The C-curve trip characteristic makes it appropriate for general-purpose loads with moderate inrush, such as lighting circuits, small motors, and control equipment. DIN rail mounting allows fast installation in standard enclosures and switchgear assemblies. The lug and screw terminal configuration accepts 14 to 4 AWG wire, covering a wide range of branch circuit conductor sizes used in commercial wiring.

Key Features

• 10 amp rating at 480Y/277 VAC for 2-pole branch circuit protection
• 10 kA interrupt rating for short-circuit fault current capability
• Thermal magnetic trip with C-curve characteristic for general-purpose loads
• DIN rail mounting for standard panel and switchgear installation
• Lug and screw terminals accept 14 to 4 AWG conductors
• IP20 enclosure rating protects against finger contact with live parts

Compatibility

Designed as an OEM-style replacement or new-installation MCB for 480Y/277 VAC 2-pole branch circuit applications using BK63HU frame components within the LS ELECTRIC BK Series lineup.

Installation Notes

Installation must be performed by a licensed electrician in accordance with NFPA 70 (NEC) requirements for branch circuit overcurrent protection. De-energize and lock out the panel before installing or replacing the breaker. Verify that conductor sizing and the available fault current at the point of installation do not exceed the breaker's 10 kA interrupt rating. DIN rail should be properly grounded and secured within a listed enclosure before mounting the breaker.
