The 3LD9200-5B, part of Siemens' SENTRON series, is classified as an auxiliary switch. This unit is equipped with one normally open (NO) and one normally closed (NC) contact, making it suitable for diverse operational needs. It can handle a rated operational voltage of up to 500V, allowing for considerable flexibility in various installations.

Its AC-15 current ratings include 6A at 110V, 3A at 230V, and 1.4A at 500V, ensuring effective service across different voltage scenarios. For DC applications, it supports a current rating of 4A at 24V according to DC-13 specifications.

Switching actions are notable; the NO contact lags when engaged and leads when disengaged. Conversely, this behavior is reversed for the NC contact, which leads when engaged and lags when disengaged. The device requires tightening torque between 0.8 and 1.2 N·m for secure mounting and operation.

It is compatible with solid wiring configurations, allowing for a dual solid wire connection size between 0.75 to 2.5 mm² and a single connection of 4 mm². Front-mounted installation simplifies setup procedures, which is supported by its compact dimensions of 0.8 inches high by 1.5 inches long and 1.5 inches wide.
