DPX3 1600 S1 3P 1000 A 36 kA circuit breaker 422541

DPX3 1600 S1 Circuit Breaker – Reliable Power Protection

The DPX3 1600 S1 is a three-pole electrical device designed to protect high-load electrical installations. With a rated continuous current of 1000 A and a high short-circuit breaking capacity of 36 kA, it ensures effective protection against overloads and short circuits. This robust solution is ideal for demanding industrial applications and advanced commercial installations.

Design and Application

This breaker features an electronic S1 trip unit, providing precise and rapid response to circuit variations. The electronic trip unit allows accurate setting of the overload current between 400 A and 1000 A, minimizing the risk of unnecessary tripping. Three auxiliary contacts enable integration with control and signaling systems. The breaker is designed for fixed mounting (not TH-rail mounting). An integrated trip indicator facilitates quick identification of the device’s status.

Advantages and Benefits

• High short-circuit breaking capacity: 36 kA at 400 V ensures effective protection against short-circuit consequences.
• Electronic S1 trip unit: Precise adjustment of overload current tailored to specific load characteristics.
• Three auxiliary contacts: Enables integration with control and signaling systems for breaker status monitoring.
• Wide rated voltage range: 220 to 690 V – universal application across various electrical networks.
• Robust construction: Fixed mounting ensures stability and reliable operation.
• Integrated undervoltage trip: Additional protection against voltage drops.
• Optional motorized drive: Enables remote control of the breaker (motorized drive available as an option).
• Protection rating IP30: Protection against contact and ingress of solid objects larger than 2.5 mm.
• Screw terminals: Ensures secure and durable connections for supply conductors.

Technical Parameters in Practice

The rated continuous current of 1000 A means the breaker is designed for prolonged operation under heavy loads without risk of overheating or damage. The adjustable overload trip range (400-1000 A) allows fine-tuning the device’s sensitivity to match specific installation requirements—lower settings trigger faster responses to overloads but increase the risk of false trips. The short-circuit breaking capacity of 36 kA at 400 V is a critical safety parameter—the higher the value, the better the breaker handles sudden current surges during faults. The option to add a motorized drive is particularly valuable for automated energy management systems or remote installation control.
