Siemens 3TJ5001-0BB4 Contactor

Siemens 3TJ5001-0BB4 Contactor is a four-pole, coil-driven switch designed for compact control panels in automation and machine-building environments, providing a robust interface between low-voltage control logic and higher-current circuits. The coil is rated at 24 V DC with a nominal power consumption around 1.2 W, enabling reliable actuation in space-constrained installations while keeping energy budgets tight in multi-pole control schemes. The device lists four contact points described as 3x N 1x N, reflecting a specific contact configuration within the 3TJ family used for control and signaling functions. As a Siemens/Furnas Electric Co product, this 3TJ5001-0BB4 is typically deployed for auxiliary switching in motor starters and control circuits where a compact, trustworthy control relay is required, and it is commonly integrated with 3TJ-series devices on DIN rail-mounted panels. Its combination of a four-pole layout and standard DIN-rail compatibility makes it suitable for panel builders and integrators seeking a reliable Siemens solution for interlocks, sequencing, and safe shutoff in conveyors, pumps, and valve actuation tasks.
