SIEMENS 3WL9111-0AD06-0AA0

Overview

SIEMENS 3WL9111-0AD06-0AA0 is a Siemens SENTRON accessory for 3WL air circuit breakers. It is configured as a closing coil, also described as shunt trip or shunt release function, designed for continuous duty with a control supply voltage of 208 to 240 V AC at 50/60 Hz, and 220 to 250 V DC. The coil is mounted on the 3WL breaker to provide electrical closing or remote tripping operation in low-voltage switchgear and motor control centers. The 3WL9111 accessory family consists of breaker-mounted spare modules and release devices for existing Siemens 3WL air circuit breaker installations. This unit is traded as an industrial MRO spare for maintenance and replacement of breaker closing or shunt trip coils.

Features

SIEMENS 3WL9111-0AD06-0AA0 combines the closing coil and shunt trip function in a 100 percent OP continuous-duty accessory. For AC operation, the control supply voltage Us is rated 208 to 240 V at 50/60 Hz; for DC operation, the compatible supply range is 220 to 250 V DC. The coil draws 40 VA closing apparent power and 8 VA operating apparent power, with 40 W closing active power and 8 W operating active power. The minimum command time at Us equal to 100 percent is 60 ms. Electrical make time is 100 ms, and the circuit breaker opening time at Us equal to 100 percent is 80 ms.

The accessory is intended for mounting on Siemens 3WL air circuit breakers in low-voltage switchgear assemblies. Short-circuit protection for the coil control circuit requires a DIAZED gG fuse link or miniature circuit breaker with tripping characteristic Class C, minimum 1 A rating according to the related accessory specification. The coil module supports remote electrical closing or shunt release operation so the breaker can be controlled from a switchgear panel, protection relay, PLC output or distributed control system. Unit weight for the 3WL9111-0AD06-0AA0 is listed at 0.743 kg by Siemens distributor data.

Principle

SIEMENS 3WL9111-0AD06-0AA0 operates as an electromagnetic actuator mounted on the 3WL air circuit breaker. When the closing coil receives the control command at its rated supply voltage, the coil energizes and drives the breaker closing mechanism, enabling the circuit breaker to be closed electrically from a remote control point. In shunt trip or shunt release operation, the same release device is energized by a protection relay, PLC or control system command and mechanically releases the breaker trip mechanism to open the circuit breaker.

The coil's apparent and active power values define the control transformer, supply contactor, fuse or PLC output rating required for the coil circuit. The command time, make time and opening time describe the electrical response sequence from control signal to breaker operation. The control supply must stay within the rated AC or DC range to ensure reliable closing or tripping, and the control circuit fuse or breaker must protect the coil wiring according to Siemens accessory guidance. Because the part is breaker-mounted, replacement should match the original 3WL breaker frame, coil voltage rating and accessory function before installation.

Applications

SIEMENS 3WL9111-0AD06-0AA0 is used in low-voltage switchgear, main distribution boards, motor control centers, power distribution panels, industrial plants, building electrical systems, utilities, water and wastewater, power plants, oil and gas, chemical processing, manufacturing lines, sugar mill and pulp mill electrical rooms, and other installations that use Siemens 3WL air circuit breakers. It serves for remote breaker closing, shunt trip release, emergency shutdown, protection relay tripping and PLC or DCS-based circuit breaker control. In existing 3WL breaker installations originally equipped with this coil, the module is a direct replacement spare for closing coil or shunt trip maintenance.
