General Electric TK123PD1A 1A 3-Pole Circuit Breaker

Meet the General Electric TK123PD1A 1A 3-Pole Circuit Breaker—a precise, three-phase protective device designed to guard three live conductors in a single, reliable package. With a dedicated 1-amp rating per circuit and a single trip mechanism, this breaker disconnects all three poles simultaneously when an overload or fault occurs, preventing partial energization and safeguarding connected equipment.

Key specifications

• Current rating: 1 A
• Poles: 3
• Part number: TK123PD1A
• Brand: General Electric

How it works and why it matters

The TK123PD1A is designed for three-phase electrical systems where coordinated protection across all phases is critical. When current exceeds the 1 A threshold or a fault triggers protection, it trips all three poles in unison. This synchronized disconnection minimizes risk from imbalanced phasing, reduces potential equipment damage, and enhances overall electrical safety in your installation.

Ideal use scenarios

• Protecting compact 3-phase machinery in commercial or light industrial settings operating at low current levels (up to 1 A per phase).
• Backup protection for small three-phase loads within GE-compatible panels and enclosures.
• Replacement or service part when exact compatibility with General Electric systems (TK123PD1A) is required.

Installation and compatibility considerations

Ensure installation in GE-approved panels or enclosures that support a 3-pole configuration. Confirm exact part number TK123PD1A and the 3-Pole, 1-Amp specification before replacement. As with all electrical work, follow local codes and consult a qualified electrician to perform installation and safety checks.

Why choose the General Electric TK123PD1A

Designed to align with GE’s design standards, this 3-pole circuit breaker delivers coordinated protection for three-phase systems with a straightforward replacement path when TK123PD1A is specified. Its focused 1 A rating and three-pole configuration offer a clean, reliable solution for protecting small, multi-phase circuits without complicating the panel layout.
