Siemens 3RV27111ED10 Circuit Breaker UL489 S00 4A

Product Description

The SIEMENS 3RV27111ED10 is a thermal magnetic circuit breaker (TMCB) rated at 4 amps, built to UL 489 standards in the compact S00 frame size. Thermal magnetic circuit breakers combine a bimetallic thermal element for overload protection with a magnetic trip mechanism for short-circuit protection, providing dual-mode overcurrent defense in a single device. This unit is designed for use in motor branch circuit and control panel applications where reliable, UL-listed overcurrent protection is required. Licensed electricians and industrial control panel builders are the typical installers of this device.

The S00 frame size makes this breaker well-suited for compact control panels and motor control centers where space is limited. At a 4-amp rating, it fits low-current motor branch circuits and control circuit protection applications common in residential, commercial, and light industrial settings. The UL 489 listing confirms it meets the standard for molded-case circuit breakers used in branch circuit protection.

Key Features

• 4-amp current rating for low-current motor and control circuit protection
• Thermal magnetic trip mechanism provides both overload and short-circuit protection
• UL 489 listed for branch circuit overcurrent protection
• Compact S00 frame size designed for space-constrained control panel installations
• Packaged individually, ready for single-unit installation

Compatibility

Designed as an OEM-style replacement or direct-fit circuit breaker for S00 frame mounting configurations in motor control and industrial control panel assemblies.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the panel or control enclosure before installing or replacing this breaker. Verify that the panel busbar and mounting rail are compatible with the S00 frame before installation. Do not exceed the 4-amp continuous rating of this device.
