2CDS213001R0161 ABB SH203-D16 16 A 3-Pole Type D 6 kA Miniature Circuit Breaker

Why Choose the ABB SH203-D16 Miniature Circuit Breaker?

The ABB SH203-D16 is a compact and dependable three-pole miniature circuit breaker (MCB) designed to provide overload and short-circuit protection in three-phase electrical circuits. As part of the ABB SH200 miniature circuit breaker series, it combines thermal-magnetic protection with a modular DIN-rail design for reliable circuit protection in electrical distribution and control systems.

This miniature circuit breaker has a 16 A rated current, Type D tripping characteristic and 6 kA rated short-circuit breaking capacity. The Type D characteristic is particularly suitable for appropriately designed circuits supplying equipment with relatively high starting or inrush currents, helping prevent unwanted tripping during normal start-up while maintaining effective overcurrent protection.

With its three-pole configuration, the SH203-D16 provides linked switching and protection across all three poles of a three-phase circuit. Its 16 A rating and modular construction make it a practical choice for suitable machinery, motor-related, control and distribution circuits requiring compact three-phase ABB circuit protection.

Key Advantages

• Reliable thermal-magnetic overload and short-circuit protection.
• 16 A rated current for suitable three-phase circuits.
• Type D tripping characteristic for loads with high starting or inrush currents.
• 6 kA short-circuit breaking capacity.
• Three-pole configuration for linked three-phase circuit protection and switching.
• Compact DIN-rail construction for straightforward installation in electrical panels.

Key Features

• ABB SH200 miniature circuit breaker series.
• 16 A rated current.
• 3-pole configuration.
• Type D tripping characteristic.
• 6 kA rated short-circuit breaking capacity.

Reliable Three-Phase Circuit Protection

Miniature circuit breakers such as the ABB SH203-D16 automatically disconnect an electrical circuit when excessive current results from an overload or short circuit. The thermal release responds to sustained overload conditions, while the magnetic release provides rapid operation during high fault-current conditions.

The Type D characteristic is intended for appropriate circuits where substantial inrush currents can occur during normal equipment start-up. Combined with its three-pole construction, 16 A rating and 6 kA breaking capacity, the SH203-D16 provides dependable protection for suitably designed three-phase machinery, control and distribution circuits.

Typical Applications

• Three-phase electrical distribution circuits.
• Industrial control and automation panels.
• Machinery and equipment circuits.
• Circuits supplying loads with high starting or inrush currents.
• Motor-related and auxiliary electrical circuits.
• DIN-rail mounted modular distribution assemblies.
