Why Choose the ABB EPX-A1B-016L3 16A Single-Pole MCCB with L3 Load Side Connector?
The ABB EPX-A1B-016L3 is a 16 A, single-pole moulded case circuit breaker (MCCB) with an L3 load side connector, designed for outgoing circuit protection within compatible ABB Protecta Power electrical distribution assemblies. Incorporating the ABB Formula A1C125 circuit breaker platform, this device provides thermal-magnetic protection against overloads and short-circuit faults in commercial and industrial low-voltage installations.
Featuring thermal-magnetic protection with the manufacturer's TMA designation, the EPX-A1B-016L3 combines thermal overload protection with magnetic short-circuit tripping. The ABB Protecta Power 16 A single-pole A1C125 configuration is specified with an 18 kA breaking capacity, providing a protective solution for appropriately designed distribution systems where the prospective fault current is within the applicable circuit breaker rating.
With a 16 A rated current, single-pole construction and L3 load side connector (LSC), the EPX-A1B-016L3 supports integration into compatible Protecta Power outgoing circuit arrangements. Its 125 A frame class provides a compact protective solution for individual circuits requiring the designated L3 connection configuration.

Reliable Thermal-Magnetic Protection for Low-Voltage Distribution
The ABB EPX-A1B-016L3 protects outgoing electrical circuits against excessive current caused by overloads and short-circuit faults. Its thermal protection mechanism responds to sustained overcurrent conditions, while magnetic protection provides rapid circuit interruption during sufficiently high fault currents. These complementary functions help protect electrical conductors, connected equipment and distribution infrastructure from damaging overcurrent conditions.
The ABB Formula A1C125 platform provides a compact protective solution for compatible Protecta Power panelboards. The EPX-A1B-016L3 combines a 16 A protective rating with an L3 load side connector for the designated outgoing connection arrangement. Electrical designers should verify the prospective short-circuit current, operating voltage, conductor sizing, terminal compatibility and distribution assembly requirements before installation.
Typical Applications
- ABB Protecta Power outgoing circuit installations.
- Commercial building electrical distribution panelboards.
- Industrial low-voltage electrical distribution systems.
- Single-phase outgoing circuits connected to L3 within compatible three-phase distribution assemblies.
- Electrical plant rooms and building services infrastructure.
- Manufacturing facilities and industrial workshops.
- Warehouses, offices and commercial premises.
