Q1: What’s the difference between your MCB and MCCB products?

A: MCB (Miniature Circuit Breaker): Protects circuits up to 125A (ideal for homes/small offices). Features fixed trip settings.

MCCB (Molded Case Circuit Breaker): Handles higher loads (up to 2,500A) with adjustable trip settings. Built for industrial/commercial use.

Q2: Can Etechin RCBOs replace separate MCB + RCD setups?

A: Yes! Our RCBOs (Residual Current Breaker with Overcurrent) combine overload/short-circuit protection + earth leakage detection in one device. Saves space and enhances safety in distribution boards.

Q3: What breaking capacities (kA) do your breakers support?

A:MCBs: 6kA–10kA (standard)

RCBOs: 6kA–10kA

Select based on your installation’s fault current risk.

Q4: Are Etechin distribution boards compatible with DIN rails?

A: Absolutely. All devices (MCB/MCCB/RCBO) mount on standard DIN rails. Enclosures support 1–4 rows with clip-on gland plates for cable entry.

Q5: Do you offer IP-rated enclosures for outdoor/harsh environments?

A: Yes. Distribution boards come in IP55 (dust/water-resistant) and IP65 (total dustproof/water-jet resistant) options. Ideal for factories, marine, or humid locations.

Q6: What certifications do your products hold?

A: All products comply with IEC/EN 60898-1 (MCB/RCBO), IEC/EN 60947-2 (MCCB), and carry CE, KEMA certifications available.

Q7: How do I select the right MCB curve (B, C, D)?

A: B-curve: Residential (sensitive electronics)

C-curve: Commercial (motors/transformers)

D-curve: Industrial (high inrush currents)

Our product datasheets include selection guides.

Q8: Can I retrofit Etechin breakers into existing panels?

A: Yes, if dimensions/compatibility align. Verify:

Pole width (1P/2P/3P/4P)

Mounting type (DIN rail)

Rated voltage/current

Consult our cross-reference guide or support team.

Q9: What’s the lead time for custom distribution boards?

A: Standard units ship in 15-20 days. Custom configurations (pre-wired/SLDs): 20-45days.

Expedited options available.
