RCCB 40 A

Dimensions:

Looking for high-level safety and reliable fire protection for your electrical installations? The two-pole (2P) RCCB / RCD Type AC with a rated current of 40 A, a sensitivity of 0.3 A (300 mA), and a short-circuit withstand capacity of 6000 A (6 kA) offers a proven, top-tier solution for protecting properties and equipment.

This model delivers the perfect balance of capacity and precision for single-phase systems in residential, commercial, and utility applications.

Why Choose a 40 A / 0.3 A RCCB (Type AC, 6 kA)?

• 300 mA (0.3 A) Fault Current – Fire Protection: Primarily designed for main or sub-panel protection, it detects earth leakage currents and prevents dangerous arcing and overheating, directly eliminating the risk of electrical fires caused by insulation faults.
• 40 A Rated Current Capacity: Provides high current-carrying capacity and stability to cover entire distribution boards or demanding single-phase circuits.
• 6000 A (6 kA) Short-Circuit Capacity: Ensures exceptional durability and safety during severe short-circuit events, protecting the internal contacts and wiring from damage.
• Type AC: Reliably detects sinusoidal AC residual currents, making it a standard and cost-effective choice for conventional electrical installations and standard loads.

Key Advantages & Quality Features

• Proven Fire Prevention: Acts as the primary shield for your property—detects minor cable or appliance insulation degradation before dangerous heating occurs.
• High Robustness (6 kA / 40 A): Heavy-duty internal mechanisms and quality contact points ensure long service life and stable performance, even under heavy loads and grid fluctuations.
• Premium Construction: Features self-extinguishing, high-density housing material for maximum thermal and mechanical stability under all operating conditions.
• Easy Functionality Testing: Equipped with an integrated TEST button for quick and simple periodic verification of the tripping mechanism.
• Fast and Secure Installation: Standard 2-pole format (2 modules) allows seamless DIN-rail mounting with heavy-duty terminal clamps for solid wire connections.
• Complete Double-Pole Isolation: Simultaneously disconnects both phase (L) and neutral (N) conductors upon fault detection, providing full isolation for safer maintenance.
• The possibility of connecting to a pin and fork bus
• Window for labeling, inscription
• Color status indicator
