V2DJ – Single Element Auxiliary Relay (DC Coil, With Indicator)
The ABB CV2DJ is a compact and reliable auxiliary relay equipped with self-reset contacts and a built-in operation indicator for instant visual feedback. Designed for DC coil operation, it ensures fast and accurate switching in control, signalling, and protection circuits. Its rugged construction and high immunity to electrical disturbances make it ideal for substations, switchgear, and industrial panels.
CV2AJ – Single Element Auxiliary Relay (AC Coil, With Indicator)
The CV2AJ variant is engineered for AC coil applications, offering the same high-quality switching performance as the DC model. The integrated operation indicator helps technicians quickly verify relay activation status during commissioning or maintenance. It is widely used in automation panels, protection circuits, and AC-based control systems.
P8nCH2J – DC Coil, With Indicator
The P8nCH2J (DC) auxiliary relay is built for dependable operation in DC-powered control circuits, offering self-reset functionality for automatic return after switching. Its operation indicator enhances visibility in busy control rooms and relay panels. Known for its durability, it is suitable for heavy-duty protection, breaker interlocking, and alarm circuits.
P8nCH2J – AC Coil, With Indicator
The P8nCH2J (AC) delivers the same robust switching performance but is optimized for AC coil environments. The self-reset mechanism guarantees consistent restoration, while the indicator simplifies status checks. This model is commonly used in power distribution boards, industrial machinery, and panel interlock systems.
P8nAHX – Without Operation Indicator
The P8nAHX is a simplified version of the P8 series, offering reliable self-reset contact operation without an indicator. It is ideal for applications where status display is not required, such as internal interlocks, hidden control panels, and compact automation systems. Despite its minimal design, it provides the same ABB reliability and long operational life.
