Information About EH3-B050

The Siemens EH3-B050 is an ITE/Siemens EH-frame molded case circuit breaker intended for low-voltage power distribution applications. It uses thermal-magnetic protection to respond to sustained overloads and short-circuit conditions. The three-pole design supports compatible three-phase systems, while the bolt-on connection allows installation in compatible panelboards and switchgear. This model is discontinued, so replacement applications should be checked against the existing equipment and breaker specifications.

Key Features:

  • 50 A Current Rating: Designed for electrical circuits with a rated current of 50 amperes.
  • 480 V AC Rating: Suitable for compatible 480 V three-phase power distribution systems.
  • Three-Pole Configuration: Provides simultaneous switching and protection across three circuit poles.
  • Thermal-Magnetic Trip Mechanism: Combines overload protection with instantaneous short-circuit response.
  • Bolt-On Mounting: Supports installation in compatible electrical panelboards and switchgear.
  • Long-Time Trip Function: Responds to sustained overload conditions according to the breaker trip characteristics.
  • Instantaneous Trip Function: Responds to high-current fault conditions to help protect connected circuits.
  • Legacy Equipment Compatibility: Intended for suitable ITE/Siemens EH-frame installations, subject to panel compatibility.

The Siemens EH3-B050 provides 50 A thermal-magnetic circuit protection for compatible three-phase industrial and commercial electrical distribution systems.
