Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Residual Current Protection: Detects and interrupts fault currents (30mA sensitivity) to prevent electric shock and fire hazards in electrical circuits.
  • Dual Compatibility: Supports both AC (230V) and DC systems, offering flexibility for diverse electrical setups.
  • Manual Control & Testing: Features a manual switch for circuit on/off and a dedicated yellow "TEST" button to verify functionality without power interruption.

Key features

  • 1. Enhanced Safety with IP20 Protection

    • With its IP20-rated plastic housing, you can ensure protection against dust and water ingress, enhancing durability compared to non-IP rated devices*.

  • 2. Quick Functionality Verification via Dedicated TEST Button

    • With the integrated TEST button, you can verify circuit protection instantly without power interruption, ensuring reliability compared to models lacking this feature*.

  • 3. Ultra-Sensitive 30mA Detection for Rapid Fault Response

    • With a 30mA residual current detection threshold, you can achieve faster fault response than traditional circuit breakers, minimizing risks of electric shock or fire*.

  • 4. Versatile 2-Pole Design for Diverse Applications

    • With its 2-pole configuration and support for AC/DC voltages up to 230V, you can install it in both residential and commercial settings, handling loads from 16A to 125A seamlessly*.

  • 5. CE Certified for Trustworthy Safety Compliance

    • With CE certification, you can ensure compliance with European safety standards, offering peace of mind compared to uncertified alternatives*.

Product details

Mcb Mccb Rccb Elcb Circuit Breaker 2p 30ma 40a C63 100a 125a Ac Dc Earth Leakage Circuit Breaker

The Gasim GSL9N RCD (Residual Current Circuit Breaker) is a 2-pole safety device designed to protect electrical circuits from earth faults and electric shock hazards. Available in rated currents from 16A to 125A, it combines robust performance with compliance to international safety standards (e.g., CE). The device features a white plastic body, a yellow TEST button for functionality verification, and an LED indicator for real-time status monitoring.

Supplier's note

  1. Three Technical Breakthroughs:

    • Faster Tripping Speed: The Pro model’s 21ms response time reduces fault exposure by 30% compared to industry benchmarks.
    • Enhanced Overload Tolerance: The Advanced model’s 170% overload capacity accommodates temporary power surges without nuisance tripping.
    • Superior Surge Protection: The Pro’s 2.6kV surge resistance safeguards sensitive equipment in industrial environments.

  2. Optimal Version Selection:

    • Residential Users: Base Model (30ms tripping) suffices for standard home circuits.
    • Commercial Spaces: Advanced Model (170% overload) handles HVAC systems and office equipment.
    • Industrial Applications: Pro Model (200% overload + 2.6kV surge) ensures reliability in high-demand settings.

    With the Pro’s tripled surge resistance compared to legacy models, you can safely power heavy machinery. Pair its 200% overload capacity with high-current appliances to avoid system downtime.

*Relative improvements compared to the Base Model.
