SPAJ142C-AA ABB Overcurrent and Earth-Fault Relay

Description:

Designed for industrial automation applications, the ABB SPAJ 142 C-AA overcurrent relay offers unparalleled precision in detecting and responding to overcurrent events.

Its robust construction and wide operating temperature range ensure reliable performance in challenging environments, making it ideal for factories, power plants, and other industrial settings.

Equipped with a single-pole double-throw (SPDT) switch, this relay provides flexible circuit control, enabling efficient and safe operation of machinery and processes.

Withstanding an impressive life cycle of at least 100,000 cycles, the SPAJ 142 C-AA is built for long-term durability, reducing maintenance costs and downtime.

Compliant with international safety standards including CE and UL, this relay ensures peace of mind for users in terms of electrical safety and compliance.

Features:

• Easy-to-use relay with the most essential functions for over-current and earth fault protection
• Three-phase, low-set phase overcurrent unit with definite time or inverse definite minimum time (IDMT) characteristic
• Three-phase, high-set phase overcurrent unit with instantaneous or definite time operation
• Low-set earth-fault unit with definite time or inverse definite minimum time (IDMT) characteristic
• High-set earth-fault unit with instantaneous or definite time operation
• Built-in circuit-breaker failure protection
• Self-supervision system continuously monitoring the operation of the electronics and the microprocessor
