UTP6A35M belongs to the miscellaneous category, and is a power device which acts like a three-pole switch that is designed with a rated operating voltage of 690 V, a continuous current rating of up to 63A, and a breaking capacity rating of 35kA. This device is suitable for AC 50Hz, rated voltage of 690V circuit for controlling and protection of motors, electric heaters, lighting, or other electric equipment for protecting against overload and short circuit.

The UTP6A35M device consists of a metal enclosure, a three-pole contact system, a thermal-magnetic overcurrent release, and mounting hardware. Inside the metal enclosure, the three-pole contact is constructed with two movable contacts and one fixed contact. The movable contacts snap onto the fixed contact when the knob on the handle is pressed and will automatically release when the knob is pushed back to the original position. A bridging switch mechanism is used to bridge the three-poles (i.e., the three-pole contact system). In order for the device to function normally, the bridging switch should be in the "on" position.

The thermal-magnetic overcurrent release works in two ways to help protect the circuit from overcurrent and short circuit. The thermal-magnetic module is comprised of a coil, a thermostat, and a bimetallic strip. When there is an overcurrent in the circuit, the thermostat will sense the increase in temperature and send a signal to the bimetallic strip, which will then bend and cut off the current. At the same time, the coil will act like a magnet, producing a magnetic field and urging the movable contacts of the three-pole contact system to open.

Apart from acting as a three-pole switch, the UTP6A35M device is also able to act as an overload protection or short-circuit protection depending on the application. This device can be used as an overload protection by installing a magnetic circuit breaker on the line of the protected circuit, while for short-circuit protection, a thermal-magnetic release must be installed on the line. That way, when a short circuit or overload occurs, the device will be tripped to shut off the circuit.

In conclusion, the UTP6A35M device is a versatile power device that can be used to control and protect a variety of electrical equipment, ranging from motors, electric heaters, and lighting to other electric equipment. It works using a three-pole contact system, a thermal-magnetic overcurrent release, and a bridging switch. The device can also be used as an overload protection or a short-circuit protection depending on the application.
