Siemens LV HRC Fuse base, flat terminal, 1-pole, 690V, 160A Part number 3NH3030

Product Overview

The Siemens 3NH3030 is a SENTRON LV HRC fuse base, size 00 (NH00), single-pole (1P), rated for up to 160 A and 690 V AC (440 V DC). It serves as a base/holder for high-rupture-capacity (HRC / NH-type) fuses, enabling safe and robust overcurrent protection for low-voltage distribution circuits, motor feeders or branch circuits that require HRC fuse protection.

Key Features

• LV HRC fuse base — size 00 (NH00)
• Single-pole fuse holder (1P)
• Rated current: 160 A
• Rated operational voltage: 690 V AC / 440 V DC
• High short-circuit breaking capacity — Icu: 120 kA (AC), 25 kA (DC)
• Flat-terminal / pad-type main current connection for secure conductor attachment
• Wide conductor cross-section acceptance (main conductors): 6 … 70 mm²; terminal strip: 1.5 … 16 mm²; box-type terminals up to 50 mm²
• Fixed-mount design — suitable for panel or switchgear installation (not bus-mounted)
• Compact dimensions and relatively low weight — ease of integration in distribution boards

Compliance & Certifications

• Compliant with international standards for low-voltage fuse systems (NH / EN 60269-1 / IEC 60269-1)
• Designed for high-rupture-capacity (HRC) fuses — suitable for industrial and commercial power distribution systems
• Rated for high short-circuit currents — suitable for power panels, distribution boards, motor feeders, and branch circuits where fault currents may be high

Applications

The 3NH3030 is ideal as a base for HRC (NH-type) fuses in power distribution boards, switchgear, motor control centres, and industrial/commercial electrical installations. Typical applications include main or sub-distribution circuit protection, feeder protection for motors or heavy loads, and circuits where high breaking capacity and reliable fuse-holder performance are required. Its single-pole, size-00 design allows compact integration where space or modular flexibility is needed.
