Installation modular contactor 63A, 3xNO + 1xNC, 230V AC STM-63-31 EXT10000301

Modular contactor for controlling and protecting circuits

This ZAMEL STM-63-31 modular installation contactor is a reliable solution for controlling electrical circuits in domestic and industrial installations. Designed for convenient mounting and aesthetic appearance, it is ideal for applications such as heating, lighting or simple automation systems. Its compact dimensions allow for easy integration with existing electrical infrastructure.

Characteristics and application

The STM-63-31 contactor is characterized by a contact arrangement of 3xNO (normally open) + 1xNC (normally closed), which provides flexibility in circuit configuration. Designed to operate at 230V AC, it can handle a maximum current of 63A in AC5b and AC7a categories – which means it copes well with both resistive (heaters) and inductive (motors) loads. The ability to cooperate with auxiliary contacts SPM-05-11 and SPM-05-20 further expands the functionality of the device, allowing for the implementation of more advanced control systems.

• Versatility: Suitable for controlling various loads – from lighting to heating and simple automation systems.
• Accessory compatibility: Compatible with auxiliary contacts SPM-05-11 and SPM-05-20, allowing for functional expansion.
• Mounting: Designed for mounting on a TH35 rail, which facilitates installation and ensures stability.
• Compact dimensions: Occupies only 3 modules in width, saving space in the switchgear cabinet.
• Safety: Provides effective protection of the circuit against overload and short circuit – like most circuit breakers in this class.

Construction and parameters

The contactor is made of high-quality materials, which guarantees its durability and reliability. The IP20 degree of protection provides protection against accidental contact and against the ingress of solid objects larger than 12.5 mm. The mounting depth is 68 mm, which should be taken into account when planning the installation. The device is designed in accordance with applicable safety standards, ensuring safe and efficient operation for a long time. The contactor design allows easy access to the terminals, facilitating connection of the wires.
