HTB2LE-40 residual current circuit breaker

It is intended for use in distribution boards where a standard MCB is replaced with a combined protection device.

Product Overview

What This Model Does

It is intended for use in distribution boards where a standard MCB is replaced with a combined protection device.

Key Benefits

  • Provides combined overload, short-circuit, and residual current protection in a single device
  • Mechanical trip mechanism ensures protection remains active during power or network failure

Who It Is For

  • Electrical wholesalers stocking residual current protection devices
  • Panel builders integrating combined protection into distribution boards
  • Switchgear assemblers specifying RCCB in custom control cabinets
  • Solar EPC contractors installing protection in PV system distribution boards
  • OEM/ODM buyers integrating a compliant residual current device into their own systems

Problems It Solves

  • An existing MCB provides no protection against earth leakage, increasing shock and fire risk
  • Installing separate MCB and RCD increases panel space and wiring complexity
  • Lack of residual current protection in older installations fails to meet modern safety standards
  • Site visits are required to manually reset a tripped RCD when no remote control is available
  • Multiple devices increase the chance of mismatched trip characteristics and coordination issues

Application Scenarios

  • Residential distribution boards where a single device replaces both MCB and RCD
  • Commercial buildings with multiple circuits requiring earth leakage protection
  • Light industrial control panels where space is limited and combined protection is needed
  • Renovations where existing DIN rail panels are upgraded to include residual current protection
  • Installations in areas with higher risk of ground faults such as kitchens, bathrooms, or outdoor circuits
Technical Features

How It Is Built

Comparison

How It Compares

Conventional MCBAdds residual current protection but requires a separate RCD for full safety
MCB plus separate RCDOne device instead of two, reducing panel space and wiring complexity

Use Guide

  1. Switch on manually and confirm the breaker holds under normal load before use
  2. Test the residual current trip function using the test button on the device
  3. Ensure the device is not overloaded and the connected load stays within 40A
  4. Keep the manual handle accessible for on-site isolation when needed
  5. Do not operate in environments exceeding the specified use temperature range
FAQ
