القاطع الكهربائي الثلاثي (MCB) قياس (40A) من (Hager)

Specifications: 3 poles, 40 A current rating, breaking capacity of 6 kA, built-in trip indicator, test button, compact design, and double quick connection terminals. It supports straightforward installation in compatible distribution boards and comes with mounting accessories for convenience.

The trip indicator shows at a glance whether the breaker has tripped. This helps you quickly identify a tripped circuit and reset or repair the corresponding wiring once the fault is addressed.

Power off the panel, mount the MCB onto the DIN rail, connect the conductors to the double quick connection terminals, secure all connections to the recommended torque, snap the MCB into place, and restore power. Use the test button to verify the device operates as expected after installation.

Ideal for protecting 3-phase circuits in residential distribution boards, light commercial panels, and small industrial circuits that require reliable overcurrent and short-circuit protection for loads sharing a 3-phase supply.

Ensure the main power is off before installation, use proper PPE, verify correct wiring and terminal torque, avoid touching live parts, and never bypass protective devices. Use only in circuits within its rated 40 A and 6 kA breaking capacity specification.

If you’re considering alternatives, you can explore other 3P MCBs like the Hager 32A 3P MCB, Schneider Electric 40A 3P MCB, or Siemens 40A 3P MCB to see differences in current ratings, breaking capacity, and pricing. Examples you can view on Fepy include: Hager 32A 3P MCB - https://fepy.com/product/hager-32a-3p-mcb; Schneider Electric 40A 3P MCB - https://fepy.com/product/schneider-electric-40a-3p-mcb; Siemens 40A 3P MCB - https://fepy.com/product/siemens-40a-3p-mcb.

Yes, it can replace other 3P MCBs that share the same frame size and mounting on a standard DIN rail. Check that the replacement has the same current rating (40 A), compatible breaking capacity, and the same mounting style and busbar connections used in your panel.

Use the built-in test button to simulate a fault condition and confirm the breaker trips as expected. After testing, reset the breaker and ensure the circuit is energised and continues to operate normally.

The MCB unit itself with its terminals is included, and mounting accessories (such as brackets or covers) may be provided. Availability of accessories can vary by listing, so check the product page for exact inclusions.

It’s designed for reliable protection of 3-phase circuits in residential, commercial, and light industrial settings. For safety-critical installations, ensure compliance with local electrical codes, verify that the MCB’s breaking capacity matches your fault-current levels, and follow proper installation practices and torque specifications.

The 40A 3P MCB from Hager offers a balance of protection and features like a trip indicator and test button, with compact terminals for easy wiring. When evaluating value, compare current rating, breaking capacity, installation ease, and price against other 3P MCB options on Fepy (for example, Schneider Electric and Siemens 40A 3P models) to choose the best fit for your panel and budget.
