Altech 3g5um Circuit Breaker 3-pole G-curve 5 Amp UL508

Product Description

The ALTECH 3g5um is a 3-pole miniature circuit breaker rated at 5 amps with a G-curve trip characteristic, listed to UL508 for use as a manual motor controller. It features a reinforced housing for improved durability in industrial panel environments. The unit ships standard with both box and ring tongue terminals, giving installers flexibility at termination. A clear cover is included to allow circuit tagging without removing protective hardware. This breaker is built on the same internals and materials as its predecessor, preserving the UL508 listing.

This circuit breaker is intended for use in industrial control panels and motor branch-circuit protection applications. The G-curve trip characteristic suits motor loads that require a tighter overload response than a standard B or C curve. Licensed electricians and panel builders typically install this device during new panel construction or retrofit work. Its compact, miniature form factor suits space-constrained enclosures common in manufacturing and process-control environments.

Key Features

• 3-pole configuration for three-phase motor circuit protection
• G-curve trip characteristic for tight overload response on motor loads
• 5-amp rating supports small fractional and integral horsepower motors
• UL508 listed for use as a manual motor controller
• Reinforced housing for enhanced durability in industrial environments
• Includes both box and ring tongue terminals as standard
• Clear cover included for easy circuit tagging without disassembly

Compatibility

Designed as a UL508-listed manual motor controller replacement or new-installation circuit breaker for 3-pole industrial control panel applications.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC Article 430 requirements for motor branch-circuit protection. De-energize the panel and verify absence of voltage before installing or replacing the breaker. Confirm that terminal torque and wire gauge requirements match the panel manufacturer specifications before making connections. Do not bypass or modify the clear cover after tagging, as it serves as a lockout-tagout aid.
