ABB 1SVR430012R0200 Time Delay Relay

ABB CT-MBS 1SVR430012R0200 Time Delay Relay is a two-changeover-contact multifunction timer in ABB’s CT-MBS family, designed for precise timing and sequencing in industrial control circuits. It supports multiple timing modes, including ON-delay, OFF-delay, impulse-on, and impulse-off, enabling flexible control of loads such as motors, conveyors, pumps, and fans. The unit is configured for star-delta starting sequences and is compatible with the 380–440 V AC range used in those applications, reflecting its role in motor-control tasks. The 1SVR430012R0200 designation identifies a CT-MBS module with two changeover contacts (2 × SPDT), allowing independent control of two circuits within a single device. This timer is intended for integration in control panels where reliable, time-based interlocking and sequencing are required to manage equipment start/stop operations reliably.
