The SRH8 series household AC contactors (hereinafter referred to as contactors) are mainly applicable to circuits with an AC frequency of 50Hz(or 60Hz), a rated working voltage up to 400V, and a rated working current up to 63A, for controlling household appliances and similar low-inductance and micro-inductance loads. They can also be used to control household electric loads, in which case the control electric power should be reduced accordingly. The product is used in homes, hotels, apartments and other places to achieve automation functions and is applied in large-scale production of household appliances.

Product Description

Application scenarios
Household electrical system: It is used to control the circuit on and off of household appliances such as electric water heaters, air conditioners, and high-power lighting equipment, achieving convenient control and protection of these appliances.
In commercial Settings such as shopping malls and supermarkets, it can be used to control lighting systems, electric roller shutters, small ventilation equipment, etc., facilitating centralized control and management.
Small industrial equipment: For some small machine tools, power tools, auxiliary equipment of automated production lines, etc., AC contactors can control the start, stop, forward and reverse rotation of motors, ensuring the normal operation of the equipment.
Product features
Electromagnetic control: Through the electromagnetic system, when the coil is energized, an electromagnetic force is generated, attracting the armature to act, thereby achieving the closing of the contacts and connecting the circuit. When the coil is de-energized, the electromagnetic force disappears, the armature returns to its original position under the action of the spring, the contacts open, and the circuit is cut off.
Low voltage release protection: When the circuit voltage drops to a certain extent (usually below 70% - 85% of the rated voltage), the contactor will automatically release and cut off the circuit, preventing equipment damage.
High operating frequency: It can meet the demands of frequent operations and is widely used in industrial automation control and motor control scenarios.

Frequently Asked Questions
What are the primary applications for the SRH8-63 AC contactor?
It is ideal for household electrical systems (heaters, AC), commercial settings (lighting, shutters), and small industrial equipment like power tools and automated production lines.
How does the electromagnetic control feature work?
When the coil is energized, it creates a force that attracts the armature to close contacts and connect the circuit. When power is cut, a spring returns the armature to open the circuit.
Does this contactor provide protection against low voltage?
Yes, it features low voltage release protection. It automatically disconnects the circuit if the voltage drops below 70% - 85% of the rated voltage to prevent equipment damage.
What is the rated current and operating voltage for this model?
The SRH8-63 model has a rated current of 63A and is designed for a rated operating voltage of 230V.
Is it suitable for high-frequency switching?
Absolutely. It is designed for high operating frequency, making it suitable for industrial automation where equipment needs to be started and stopped frequently.
What is the pole configuration of the SRH8-63?
This specific AC contactor is a 2P (two-pole) device with a rated insulation voltage of 500V.
