ABB 703153K05 20A 1-Pole 240 V Circuit Breaker

The ABB 703153K05 is a compact, reliable 20A 1-pole 240 V circuit breaker designed to protect individual 240V circuits within compatible electrical panels. Built for consistent performance, this ABB component helps ensure electrical safety and equipment protection in both residential and light commercial installations.

Key specifications

• Current rating: 20 A
• Poles: 1
• Voltage rating: 240 V
• Part number: 703153K05

What makes it different

Unlike generic breakers, the ABB 703153K05 is designed to align with ABB panels and compatible distribution systems. Its single-pole configuration provides straightforward protection for a dedicated 240V circuit, helping to prevent overheating, nuisance trips, and electrical fires when overload or short circuits occur. The clear part-number traceability (703153K05) simplifies replacement and maintenance in established systems.

Ideal use cases

• Protecting 240V branch circuits in residential or light commercial panels, such as dedicated outlets, HVAC equipment, or heavy-duty tools connected to a 240V supply.
• Replacement or upgrade for legacy installations that require a 20A, 1-pole 240V ABB breaker by part number 703153K05.
• Components of a modular protection setup where easy replacement and traceability matter for ongoing maintenance.

How to use

Install the breaker in compatible slots designed for 1-pole 240V protective devices. Verify that your panel accepts 1-pole 240V breakers and that the circuit requires a 20A rating. After installation, test the circuit with appropriate tools to confirm proper trip behavior and reliable protection.

Customer considerations

If your project specifies a 20A, 1-pole, 240V ABB breaker by part number 703153K05, this device offers a reliable, manufacturer-supported option that aligns with ABB’s protection philosophy and equipment compatibility.
