3VA4140-4ED14-0AA0 - 40 Amp Circuit Breaker

3VA4140-4ED14-0AA0  -  40 Amp Circuit Breaker

Safeguard your panel with the Siemens 3VA4140-4ED14-0AA0 — a compact, high-performance 40 A molded-case circuit breaker engineered for dependable protection. Whether you're building a new electrical system or upgrading an existing one, this breaker reacts swiftly to overloads and short circuits to minimize downtime and equipment damage. Its slim profile and lightweight design make installation fast and neat, while its internal TM210 thermal-magnetic trip unit ensures precise fault detection that's firm but fair.

Key Features & Benefits

• 40 Amp Capacity: Ideal for branch circuits requiring stable protection without oversizing.
• Thermal-Magnetic Trip (TM210): Combines thermal (overload) and magnetic (short-circuit) response for accurate, timely protection.
• High Interrupting Rating: Rated for 25 kA at 480 V AC (25 kA @ 480 Y/277), giving you reliable performance even during surge events.
• Class S (SEAB) Breaking Capacity: Offers standard breaking capacity in line with UL/IEC norms.
• Compact & Installer-Friendly: Approx. 5.09 in (129.4 mm) in height, with a depth and width suitable for tight panel spaces.
• Load-Side Lugs Ready: Makes wiring quicker and cleaner, decreasing installation time.
• Thermal Consistency: Maintains performance across a wide temperature range, from –25 °C to +70 °C.
