Eaton PLSM-B16/3-MW Miniature Circuit Breaker, 3-Pole, B-Characteristic, 16A, 10kA

The Eaton PLSM-B16/3-MW is a professional-grade 3-pole miniature circuit breaker engineered to provide robust protection for electrical circuits in both residential and commercial environments. This device is designed to detect and interrupt overcurrents, specifically addressing both overload and short-circuit conditions to prevent damage to wiring and connected equipment. With its reliable B-characteristic tripping curve and a 16A rated current, it ensures precise performance in standard electrical distribution systems.

Advantages

This circuit breaker stands out due to its high breaking capacity of 10kA, which allows it to safely handle significant fault currents. The 3-pole configuration makes it ideal for protecting three-phase systems, ensuring that all phases are disconnected simultaneously during a fault. Its compact design facilitates easy installation in standard distribution boards, while the high-quality construction materials guarantee long-term operational reliability and durability under continuous use.

Suitable for

• Protection of three-phase electrical circuits in residential buildings
• Safeguarding commercial lighting and power distribution systems
• Overload and short-circuit protection for general electrical installations

When it may not be suitable

This device is not intended for use in DC electrical systems, as it is specifically rated for AC applications. Furthermore, it may not be suitable for circuits with high inrush currents, such as those powering large motors or transformers, where a C or D characteristic breaker might be required instead.

Key specifications

• Number of poles: 3
• Rated current: 16A
• Tripping characteristic: B
• Breaking capacity: 10kA
• System type: AC

How to use

The circuit breaker should be installed by a qualified electrician onto a standard DIN rail within a distribution board. Ensure that the supply cables are securely connected to the input terminals and the load cables to the output terminals, following the torque specifications provided by the manufacturer. Once installed, the device is operated via the front-mounted toggle switch, which indicates the status of the circuit.

What to consider before purchase

• Verify that the 16A rating matches the requirements of your electrical circuit
• Ensure the B-characteristic is appropriate for your specific load type
• Confirm that your distribution board has sufficient space for a 3-pole modular device

Usage recommendations

Regularly inspect the circuit breaker for signs of physical damage or overheating. It is recommended to perform periodic testing of the installation to ensure that the protection mechanisms remain fully functional over time.
