PT270615 Relays

Power Relays, Over 2 Amps

PT270615 is a power relay with a rated operational current of 2 amperes and above. It is a SPDT or DPDT (single pole double throw or double pole double throw) type of standard relay. It is designed for use in applications that require a relay with a high current rating and short response time. The applications of the PT270615 ranges from appliance and motor controls to power supply switching, circuit protection, and many others.

Applications

PT270615 is mainly used in power supply switching, circuit protection and motor controls applications. In power supply switching, the relay is used to control the switching of the power supply to the electrical device. In a circuit protection application, the PT270615 may be used in a circuit breaker to prevent the overloading and overcurrenting of circuits. In motor controls, the relay can be used to control the start and stop of electric motors as required.

PT270615 can also be used as an HVAC control device, in order to control the temperature of a room or other space. Additionally, PT270615 can be used in industrial automation applications, such as factory production lines, for controlling the speed and timing of various mechanical processes.

Features

The PT270615 features a low contact resistance resistance (5 mOhm max) and a high response time of 5ms maximum. It is also UL and CUL recognized, and compatible with most major HVAC control systems. The rated current of 2 amperes is suitable for most applications, and the relay also has low power consumption to ensure long-term operating efficiency.

Construction and Working Principle

The PT270615 is a miniature, enclosed power relay with metal and plastic parts. It has an arc resistant enclosure and is designed with a threaded base for secure installation. The bottom part of the device includes a coil, which is connected to two sets of contact blocks. When the coil is energized via a suitable voltage signal, it induces a magnetic field around the coil and pulls the two contact blocks together, thus closing the circuit.

The voltage input to the relay must be within the rated operating range or else the relay won’t work properly. When the voltage input decreases below a preset value, the contact blocks open again, thus breaking the circuit. The PT270615 is a reliable and economical solution for a range of motor control applications, and its low contact resistance makes it suitable for use in even the most demanding environments.
