Siemens 3NP4076-1CF01 3-pole fuse disconnector

Siemens SENTRON 3NP4076-1CF01 Overview

The Siemens SENTRON 3NP4076-1CF01 is a 3-pole fuse switch disconnector, size NH1. It is used for the safe disconnection and connection of circuits and provides overcurrent protection (via fuses) for devices in low-voltage power distribution systems.

Product Detailed Description

• Function:

• Isolating Function: Provides reliable electrical isolation of circuits during maintenance or repair work, ensuring the safety of operating personnel.

• Switching Function: Enables the connection and disconnection of circuits under normal operating conditions.

• Overcurrent Protection: In conjunction with suitable NH fuses, it interrupts the circuit in the event of overload or short-circuit faults, protecting downstream equipment.

• Visible Disconnection Indication: Provides a clear visual indication of the contact position, enhancing safety.

• Features:

• 3-Pole: For three-phase AC circuits.

• Size NH1: Suitable for NH1 size fuses. NH fuses are a common low-voltage fuse standard.

• Direct Operation: The handle is directly connected to the switching contacts.

• Front-Operated: The operating handle is located on the front of the switch.

• Fixed Mounting: Secured with screws for fixed installation.

• IP20 Degree of Protection: Provides protection against the ingress of solid foreign bodies (greater than 12.5 mm).

• Complies with IEC 60947-3: Meets the international standard for low-voltage switchgear and controlgear.
