Power relay, over 2 Amps, is the main category for the PT370S15 application field and working principle. Power relay, which is also known as contactors, is an electric switch device that is used to control and draw additional current on an electrical system. The relay contacts can be used in a variety of applications, including industrial, automotive, and military applications.

The PT370S15 Power Relay is rated up to 30 Amps with an operating voltage of up to 400 Volts. It features a contact gap of 0.5 mm, a contact spacing of 18.2 mm, a contact engagement depth of 1 mm, a contact disengagement depth of 1.3 mm, and a mounting hole of 2 mm. It also has a complete plastic contact package, with all three of the contacts connected to a ternary frame base. The contacts are connected to a flexible multi-branch plunger and two contact pins are affixed to the plunger. The striking mechanism is mounted on the armature.

The PT370S15 Power Relay provides a wide range of features and benefits. It offers exceptional heat dissipation, low voltage dropping, low on-resistance, good static contact resistance, and low leakage current. It also has improved radio frequency interference (RFI) protection, short circuit protection, and dielectric strength. Additionally, it has ceramic terminal boxes for protecting contact points from dust and dirt.

The working principle of the PT370S15 Power Relay is based on the simple ON-OFF operating principle. When the power is turned on, the armature is lifted and the plunger opens the contact gap, allowing current to flow through the circuit. When the power is turned off, the armature is released and the plunger closes the contact gap, interrupting the current flow through the circuit.

The PT370S15 Power Relay application field is diverse due to its wide operating range and reliable performance. It is used in general electrical equipment like motors, starters, and lighting systems. It can also be used in safety systems like emergency stop systems, relay switching systems, and door locks. In industrial automation systems, it is usually used as a contact switch to activate or deactivate a large number of machines. It can also be used to switch valves in fluid control systems and for actuating solenoids.

The PT370S15 Power Relay is an ideal choice for applications that require reliable and cost-effective switching of electric currents over 2 Amps. With its high efficiency, robust design, and excellent performance characteristics, the PT370S15 is highly suitable for automation and safety systems. Its wide operating voltage range and reliable switching action make it a versatile and versatile device for many different industries.
