Frequently Asked Questions: ABB SH203M-C32NA Miniature Circuit Breaker
The ABB SH203M-C32NA MCB is designed to provide reliable electrical protection for industrial and commercial applications. Its main function is to safeguard electrical circuits from overcurrents and short circuits, thereby preventing damage to equipment and reducing the risk of electrical hazards.
This MCB is a 4-pole (4P) device with a C-curve characteristic and a rated current of 32 Amperes. It is designed for a voltage and frequency of 50/60 Hz and has a dielectric test voltage of 2 kV. It also boasts an electrical endurance of 10,000 AC cycles and a mechanical endurance of 20,000 cycles, indicating its long-lasting performance and durability.
The MCB features cage-type screw terminals with a tightening torque of 2 N·m, ensuring secure and stable connections. It can accommodate flexible conductors with ferrules (0.75 – 16 mm²), rigid conductors (0.75 – 25 mm²), and stranded conductors (0.75 – 25 mm²). The device is also compliant with DIN 43880 standards for installation size. Notably, it supports arbitrary power supply connection, offering flexibility in wiring configurations.
The “C-curve” refers to the tripping characteristic of the circuit breaker. C-curve MCBs are typically used for inductive loads with moderate inrush currents, such as lighting and general-purpose circuits. The “4P” designation indicates that this is a four-pole circuit breaker, meaning it can interrupt all four conductors (typically three phases and neutral) in a three-phase electrical system, providing comprehensive protection.
This MCB is manufactured using high-quality insulating materials (Group II, Black, Sealable) to ensure electrical safety and longevity. Its high mechanical endurance (20,000 cycles) contributes to its durability. The secure screw terminals, requiring a 2 N·m tightening torque, help prevent loose wiring and potential hazards. Additionally, it has an ON/OFF indicator on the toggle switch for easy operational status identification.
The ABB SH203M-C32NA MCB can be purchased from Shansen Enterprises in Coimbatore, an authorized channel partner of ABB in India. They offer a wide range of ABB products, including other MCBs, RCCBs (Residual Current Circuit Breakers), contactors, relays, and pilot lights. They serve homes, apartments, office complexes, and industries across India and claim to have ready stock with quick dispatch within 48 hours.
The ABB SH203M-C32NA has an Energy Limiting Class 3 rating. This classification indicates the MCB’s ability to quickly interrupt fault currents, limiting the let-through energy during a short circuit. A higher energy limiting class (like Class 3) generally means better protection for downstream equipment due to the reduced energy stress during a fault.
