B8E,S8E Low Voltage Secondary Connector
B8E,S8E Low Voltage Secondary Connector
Low Voltage Secondary Connector – S8E / B8E Series
*For MNS2.0 / GCS low voltage drawout switchgear*
The S8E / B8E series secondary connectors are designed for auxiliary circuit connection in low voltage drawout switchgear (MCC), specifically for MNS2.0 and GCS type drawer units. They provide reliable plug‑in/out performance for control, metering, and protection signals.
These connectors are available with pre‑wired cables (1.5mm² or 2.5mm², length 900mm), simplifying field wiring and reducing assembly time.

Secondary Connector
In standard drawer designs, primary and secondary circuits often make/break at the same time, which may not be desirable for some control schemes. The DTC‑1.21 extended secondary connector provides a longer travel, ensuring secondary circuits remain connected while primary is disconnected (or vice versa), allowing safer testing and sequencing.
*DTC‑1.21 corrects the defect of simultaneous primary/secondary circuit switching in standard drawers.*
When ordering, please specify:
- Series (B8E / S8E / DTC‑1.21)
- Number of contacts (e.g., 8, 16)
- Wire size (1.5mm² or 2.5mm²)
- Wire length (standard 900mm or custom)
- Type (moving plug or fixed socket)
- For special requirements, please contact our technical department.
