Its wide range makes it adaptable for various power requirements, delivering dependable protection while preventing nuisance tripping and maintaining an impenetrable defense against electrical anomalies.
Engineered with a formidable 4.5kA breaking capacity, this mini circuit breaker effectively handles severe overloads and catastrophic short circuits. The advanced 1P+N pole configuration offers a distinct safety advantage by actively protecting the phase while simultaneously disconnecting the neutral line during a fault. This complete electrical isolation drastically reduces shock hazards for maintenance personnel. By instantly extinguishing fault arcs and severing the power flow, it provides unparalleled electrical fault protection, ensuring the safety of your system, safeguarding expensive downstream equipment, and preventing potential damage to the entire electrical grid.
The DPN MCB boasts a long lifespan constructed to endure the most demanding operational environments, with rigorously tested 2000 electrical cycles and an impressive 10000 mechanical cycles. Every time the toggle is engaged, operators will notice a crisp, authoritative snap—a tactile confirmation of the precision-engineered internal mechanics. This exceptional durability ensures reduced maintenance and extends the product’s service life, making it a cost-effective choice for long-term use. For facility managers and professional panel builders, specifying a component with such robust mechanical endurance means fewer replacements and lower long-term operational costs.
Designed with the installer's workflow in mind, this 1P+N MCB is fully compatible with standard 35mm DIN rail installation, making setup straightforward and quick. The terminal design accommodates large cross-sectional area cables up to 10mm², providing a secure, high-surface-area connection that minimizes electrical resistance. Furthermore, the terminals flawlessly integrate with both pin-type and fork-type connection combs (busbars), accelerating the wiring process during high-volume panel assembly. Its ergonomic design simplifies the installation process, whether for new builds or retrofitting existing systems, ensuring neat, organized, and highly reliable power distribution.
The internal architecture of the DPN 1P+N 2holes Mini Circuit Breaker (MCB) incorporates high-quality electrical contacts crafted from specialized silver-alloy, which ensure excellent conductivity and minimal wear over time. These meticulously finished contact points virtually eliminate the risk of micro-welding or pitting during continuous operation. These contacts are made from durable materials that help maintain a remarkably low temperature rise during heavy load conditions, keeping the exterior cool to the touch. This thermal stability guarantees unwavering, stable performance in both densely packed residential consumer units and heavy-duty industrial environments.
The outer shell of the MCB housing is constructed from an advanced fire-resistant plastic polymer, designed to endure extreme temperatures and physical impact without deformation. This robust housing ensures reliable protection against accidental fires and electrical hazards in harsh conditions. Furthermore, it features a highly optimized physical footprint:
Ultra-Compact 18mm Profile: The narrow single-module width frees up valuable real estate inside distribution boards.
High-Density Panel Optimization: The slim design allows for more circuits to be packed into smaller enclosures, ideal for space-constrained environments.
Impact Resistance: The textured exterior resists scratches and withstands the physical impacts typical of busy construction sites.
At the heart of this 1P+N circuit breaker lies a highly sophisticated dual-action defense system. It features a precision-calibrated bimetallic thermal mechanism to slowly bend and protect against prolonged overloads, safeguarding wiring insulation from heat degradation. Complementing this is a highly responsive electromagnetic magnetic mechanism dedicated to instantaneous short-circuit protection, shattering the circuit in milliseconds when massive fault currents surge. These dual mechanisms work in perfect harmony to provide enhanced electrical fault protection, ensuring the circuit remains entirely safe under wildly varying load conditions and unpredictable power surges.
The standardized 35mm DIN rail clip design is engineered from high-tension steel, providing a vice-like grip that facilitates quick and hassle-free installation while preventing vibration loosening. Beyond standard mounting, this breaker boasts exceptional accessory expandability. The modular side-profile allows technicians to quickly snap on auxiliary components such as shunt trips, auxiliary contacts, alarm switches, or over/under-voltage protectors. Whether it’s a simple new electrical installation or a complex automated system upgrade requiring remote monitoring, this feature makes the DPN 1P+N MCB suitable for various setups, vastly improving installation efficiency and reliability.
