ABB 2RCA013655A0001H power relay accessories

Product Overview

2RCA013655A0001H is a specialized power relay in the ABB relay series, designed specifically for industrial circuit control. Its core function is to achieve on-off control of high-power load circuits through small control current signals, while also having circuit isolation function to effectively avoid the influence of load side interference on the control circuit. This relay adopts a modular structure design, compatible with standard rail installation methods, and can be quickly integrated into various control cabinets to adapt to different brands of control equipment. It adopts high-quality contact materials and optimized electromagnetic structure internally to ensure stable performance even in frequent switching scenarios, meeting the long-term continuous operation needs of industrial sites.

Core functional features

1. Reliable circuit on-off control

The core function of this power relay is to achieve precise linkage between the control circuit and the load circuit. By receiving electrical signals from the control end (such as PLC output signals), it drives the internal electromagnetic mechanism to operate, thereby controlling the closing and opening of the main contacts and achieving on/off management of the power circuit. Its contact switching response is fast, the action time is short, and it can accurately execute control instructions. Whether it is single start stop control or periodic switching scenarios, it can maintain stable action consistency, avoiding circuit failures caused by contact adhesion and action delay.

2. Efficient electrical isolation

Built in reinforced electromagnetic isolation structure, electrically isolates the control circuit from the load circuit. The isolation voltage level meets industrial safety standards and can effectively block the impact of voltage fluctuations, surge surges, and electromagnetic interference on the control circuit on the load side. At the same time, it prevents control circuit failures from being transmitted to the load end, improving the anti-interference ability and operational safety of the entire control system. This isolation characteristic makes it particularly prominent in industrial environments with high voltage and strong interference.

3. Overload and surge protection

The relay integrates overload protection and surge suppression mechanisms internally. When the load circuit experiences overload current, its built-in protection structure can quickly respond and achieve circuit protection through contact disconnection or signal feedback, avoiding relay burnout or load equipment damage caused by overload. At the same time, it has a certain tolerance for potential transient surge voltages in the circuit, reducing the impact of surges on contacts and internal components, and extending the product's service life.

4. Convenient installation and maintenance

Adopting industrial standard rail installation design, compatible with 35mm DIN rail, the installation process is simple and efficient, without the need for complex fixed structures, and can quickly complete layout combinations with other control components. The relay housing is made of transparent or semi transparent flame-retardant materials, which facilitates on-site personnel to visually observe the internal contact status and indicator light signals, and detect abnormal situations in a timely manner. In addition, its pin layout is standardized, and the wiring terminals adopt a crimping design, which makes the wiring firm and easy to disassemble, reducing maintenance costs.
