Functional Features

OVERLOAD & SHORT CIRCUIT PROTECTION: It is a thermal magnetic circuit breaker, combining thermal overload protection and magnetic short circuit protection. When the current in the circuit exceeds the rated value, the thermal element will be deformed due to the heat generated by the overload current, triggering the release mechanism to cut off the circuit; when a short-circuit fault occurs, the strong magnetic field generated by the short-circuit current will cause the electromagnetic release to act instantaneously, quickly cutting off the power supply and protecting the equipment and lines from damage caused by the overload and short-circuit.

Manual reset: after an overload or short-circuit event, the circuit breaker will cut off the power supply, and manual operation is required to switch the circuit breaker switch to the reset position in order to restore the power supply.

High disconnecting capacity: with high disconnecting capacity, it can reliably cut off the circuit in case of high fault current to ensure the safety of power system.

Technical parameters

Rated voltage: usually 120/240V AC, but there may be other voltage levels available to adapt to different application scenarios.

Rated current: There are various rated current levels available, which can be configured according to the actual load demand, generally covering the range from small current to large current, such as common 10A, 16A, 20A, 32A, etc.

Short-circuit breaking capacity: generally between thousands of amperes to tens of thousands of amperes, can quickly cut off the circuit when short-circuit fault occurs, to protect the safety of equipment and lines.

Application Scenario

Industrial control system: In the industrial production of automated production lines, PLC control systems, inverters, servo drives and other equipment power input, can be used as the main power protection device to prevent equipment damage due to power failure, to ensure the continuity and stability of the production process.

Commercial and office facilities: widely used in shopping malls, office buildings, hotels and other places in the electrical equipment, such as air conditioning, elevators, copiers, printers, lighting systems, etc., when the equipment is abnormal, cut off the power supply in a timely manner, to prevent damage to the equipment and the occurrence of safety accidents.

Data center and communication base station: in the data center servers, switches, UPS and other equipment, as well as communication base station communication equipment, as a power protection device, to ensure reliable power supply to the equipment, to prevent data loss and communication interruption due to power failure and other problems.

The transfer sequence of OTM_C21D can be summarized in following steps: 

• An anomaly occurs on the Line 1 (LN1) 

• Generator start, immediately start generator in case of black-out, phase-loss, overvoltage or undervoltage (If Generator mode is selected) 

• The Line 2 start the normal functioning,  transfer delay Ts 

• Change-over switch (Switch I) to the position 0 

• Change-over switch (Switch II) to the  position II

And the return sequence can be summarized in  the following steps: 

• The Line 1 will start the normal functioning 

• Change-over switch stays in position II 

• An anomaly occurs on the Line 2 (LN2) 

• Change-over switch stays in position II 

• Change-over switch can be transferred  manually back to position I
