1P AC Miniature Circuit Breaker

The PuGao Mora PLS-60H 1P AC Miniature Circuit Breaker is a modular low-voltage protection device specifically designed for the on/off and safety protection of single-phase AC line live wires. The device integrates dual protection mechanisms of thermal and magnetic tripping. When abnormal current occurs in the circuit, it can automatically cut off the circuit, avoiding cable overheating, electrical fires, and the burning of backend electrical equipment, ensuring personal and distribution system safety.

The single pole structure is only 18mm wide, making it easy and compact to install. Paired with a 35mm standard DIN rail buckle, it can be quickly installed, disassembled, and replaced, making it very suitable for scenarios where the internal space of the distribution box is limited.

Mora PLS-60H 1P AC miniature circuit breaker, rated current C63, rated voltage 230/400V AC, breaking capacity 10kA, compliant with IEC 60898-1.

It is AC type MCB for single-phase power distribution system. It provides overload and short-circuit protection, no residual current protection. 1-pole design. Mounted on standard 35mm DIN rail, widely used in residential and commercial distribution cabinets.

Advantages

Under long-term overload conditions, the internal bimetallic strip undergoes thermal deformation, achieving delayed tripping and avoiding misoperation caused by normal starting current of household appliances; Once a short circuit or instantaneous high current surge occurs, the electromagnetic mechanism of Mora PLS-60H 1P AC Miniature Circuit Breaker can quickly disconnect and isolate the faulty circuit within 0.1 seconds.

Built in multi-layer grid arc extinguishing components. At the moment of breaking the current, the arc is quickly divided and cooled, reducing the erosion of the contact caused by the arc, extending the service life of the circuit breaker, and improving the stability of repeated on-off.

Silver alloy contact material effectively reduces contact resistance, reduces long-term heat generation, is resistant to arc erosion, and maintains reliable conductivity even after repeated opening and closing.

PA66 flame retardant nylon shell, anti-aging, not easy to deform. When encountering abnormal high temperatures, it will not melt or support combustion, greatly reducing the risk of fire in the distribution box.

The mechanical status window visually displays the ON/OFF status of the switch, allowing operation and maintenance personnel to judge the switch status at a glance during maintenance, reducing the risk of misoperation.

Application：

1P AC Miniature Circuit Breaker is selected for the household lighting branch; Wall mounted circuit with 1P 20A circuit breaker. When the aging of the circuit causes overload, the circuit breaker automatically trips to prevent the internal circuit of the wall from catching fire. Tip: 1P only disconnects the live wire. When there is a need for leakage protection, it needs to be used in conjunction with a leakage protector.

The small fan, signal module, and low-power control circuit inside the industrial control cabinet use this 1P MCB for front-end protection. Single module compact size, saving valuable installation space inside the cabinet.

The AC output branch of household small photovoltaic systems is isolated and protected against overcurrent using a 1P AC Miniature Circuit Breaker. During maintenance, the circuit can be disconnected to ensure both operational safety and overload protection.

2. The 1P AC Miniature Circuit Breaker only cuts off the live wire, while the neutral wire remains connected;

3. It is recommended to conduct regular inspections for long-term operating projects;

4. Select and match the rated current and breaking capacity according to local electrical regulations and actual loads.

FAQ

Q: What is the difference between 1P and 2P miniature circuit breakers?

A: 1P only connects and disconnects live wires, which is smaller in size and lower in cost, and is mostly used for branch circuit protection; 2P can simultaneously cut off the live and neutral wires, suitable for scenarios that require complete isolation of the circuit.

Q: What does the C-curve represent?

A: The C-curve is suitable for common resistive and mildly inductive loads such as lighting and household sockets, and can withstand short-term startup surge currents of equipment without easily tripping.
