2CDS212001R0981 ABB SH202-D0.5 Miniature Circuit Breaker 0.5 A Type D 6 kA 2P

Why Choose the ABB SH202-D0.5 Miniature Circuit Breaker?

The ABB SH202-D0.5 is a compact and reliable 2-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits. As part of the ABB SH200 series, it provides dependable thermal-magnetic circuit protection for low-current electrical distribution and control applications.

Featuring a Type D tripping characteristic, the SH202-D0.5 is particularly suitable for appropriately designed circuits supplying equipment with relatively high starting or inrush currents. Its 2-pole configuration provides simultaneous switching and overcurrent protection across both poles, making it suitable for circuits requiring two-pole disconnection.

With a rated current of 0.5 A and a 6 kA rated short-circuit breaking capacity, the SH202-D0.5 combines low-current circuit protection with the inrush tolerance associated with a Type D characteristic.

Key Advantages

• Reliable overload and short-circuit protection.
• 0.5 A rated current for low-current electrical circuits.
• 2-pole configuration for simultaneous circuit disconnection.
• Type D tripping characteristic suitable for loads with relatively high starting or inrush currents.
• 6 kA rated short-circuit breaking capacity.
• Compact modular construction for straightforward DIN-rail installation.

Key Features

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

Reliable Two-Pole Circuit Protection

Miniature circuit breakers such as the ABB SH202-D0.5 automatically disconnect a circuit when excessive current results from an overload or short circuit. Its two-pole arrangement provides coordinated switching and overcurrent protection, supporting convenient isolation of appropriately designed electrical circuits.

The Type D characteristic provides increased tolerance of short-duration inrush currents compared with Type B and Type C characteristics, making the SH202-D0.5 suitable for low-current circuits where connected equipment can produce comparatively high transient starting currents.

Typical Applications

• Low-current electrical distribution circuits.
• Two-pole control circuit protection.
• Control and automation equipment.
• Circuits requiring simultaneous two-pole disconnection.
• Low-current loads with relatively high starting or inrush currents.
• Modular electrical distribution and control panels.
