Suntree 160A 4 Pole AC MCCB Circuit Breaker

Description

Overview

The Suntree 160A 4 Pole AC MCCB Circuit Breaker is designed to protect medium and heavy load electrical distribution systems from overload faults and short circuit conditions. It provides dependable circuit isolation and stable protection for three-phase installations that require neutral protection support.

Key Protection Features

• Protects against overloads and short circuits

• Provides circuit isolation during abnormal conditions

• Reduces equipment damage risk

• Improves operational safety across connected loads

4-Pole Design for Three Phase + Neutral

The 4-pole configuration improves safety by disconnecting all active conductors during abnormal electrical conditions. This breaker is suitable for:

• Inverter output protection

• Generator distribution panels

• Main incoming feeders

• Industrial switchboards

Thermal Magnetic Trip Mechanism

The breaker uses a thermal magnetic trip mechanism that responds quickly to:

• Overload current (thermal response)

• Instant fault current (magnetic response)

This ensures fast interruption and stable protection.

Compact & Easy to Install

The compact enclosure allows easy installation inside:

• Panel boards

• Hybrid solar systems

• Distribution boxes

Expandable with Accessories

Supports integration with optional accessories for advanced monitoring and remote control:

• Auxiliary contacts

• Alarm contacts

• Undervoltage release modules

• Shunt trip units

Built for Demanding Environments

• Flame retardant insulated housing

• High endurance switching components

• Performs reliably in commercial and industrial environments

• Complies with IEC protection standards

• Ensures stable long-term operation across distribution networks

Ideal Applications

This device is ideal for protecting:

• Solar hybrid inverter outputs

• Commercial distribution boards

• Generator changeover panels

• Factory electrical systems
