Siemens ED41B020L - 20 A, 120 V, 1-Pole Circuit Breaker | AmpState

Siemens ED41B020L is a 20A, 120V, 1-pole molded case circuit breaker designed to deliver dependable branch circuit protection in panelboards and load centers. Its compact form frees valuable panel space while providing precise thermal-magnetic protection that reacts quickly to overcurrent and short-circuit events.

Why this breaker stands out

• Space-efficient design: A compact molded-case footprint maximizes usable panel area without sacrificing protection performance.
• Thermal-magnetic trip unit: Combines thermal sensing for sustained overload and magnetic trip for immediate response to short circuits, giving stable, repeatable protection.
• One-pole, 20A at 120V: Ideal for single-circuit protection of lighting, receptacles, and control circuits in residential, commercial, and light industrial settings.
• OEM-compatible reliability: Seamlessly compatible with matching Siemens OEM load centers and panelboards for straightforward upgrades, replacements, or panel expansions.
• Easy installation and predictable behavior: Designed for dependable performance with clear, repeatable trip characteristics and simple reset after a fault.

Where it shines in real-world use

• Safeguard individual lighting and outlet circuits in homes, apartments, or townhomes, reducing fire risk and equipment damage from faults.
• Commercial: Suitable for small office spaces, retail fixtures, and service panels where compact protection is essential and panel density matters.
• Light industrial: Protects simple 120V loads and control circuits in compact equipment enclosures, helping maintain uptime with reliable interruption when needed.

What to expect from its protection profile

The ED41B020L’s thermal-magnetic approach delivers stable protection during normal operation and swift interruption during short-circuit faults. This reduces nuisance trips from brief surges while ensuring serious faults are halted quickly, preserving downstream devices and wiring.
