Siemens EE3M020 20A 3-Pole 240 V Circuit Breaker

Siemens EE3M020 20A 3-Pole 240 V Circuit Breaker is a rugged protective device engineered to safeguard 240-volt circuits in commercial and industrial electrical panels. This genuine Siemens part (EE3M020) delivers dependable, multi-pole interruption to help keep wiring, equipment, and people safe during overloads and fault conditions.

Designed with three poles, this breaker interrupts all three conductors simultaneously, ensuring coordinated protection across multi-wire or three-phase systems. With a 20-amp current rating, it provides precise, reliable protection for circuits that require higher load handling and robust fault response, aligned with professional electrical standards.

• Current rating: 20 A
• Poles: 3
• Voltage rating: 240 V
• Part number: EE3M020
• Brand: Siemens

This circuit breaker is ideal for protecting 240V circuits in settings that rely on Siemens panel configurations and EE-series protection. It’s particularly suitable for 3-wire or multi-pole applications where simultaneous disconnection of all poles is essential for safety and compliance.

Key use cases:

• Protection of 240V circuits in commercial or industrial panels
• Protection for three-wire or three-phase equipment and equipment racks
• Replacement part for Siemens panels that accept EE-series breakers

Practical notes for installation and compatibility: verify that your electrical panel accepts the EE3M020 style and that the replacement part matches the panel’s listing and qualification. Proper torque and electrical connection practices apply to ensure reliable operation and safe interlock behavior.

For professionals seeking a trusted, authentic Siemens solution, the EE3M020 delivers clear performance benefits: rugged construction, precise 20-amp protection, and coordinated three-pole interrupt capability for safer, more predictable electrical protection in 240-volt systems.
