At 6 A, this handles sustained loads up to 1.38 kW on a 230 V line, with the magnetic trip clearing short-circuit faults before the thermal element sees them. For DC circuits, the IEC 60947-2 rating is 15 kA at 72 V DC maximum. Under UL 1077 (supplementary protector listing), it carries 5 kA at 230 V AC. Overvoltage category III (OVC III) means it's rated for fixed-installation distribution boards, not just socket-outlet circuits. The 1P+N configuration with switched neutral is common in IEC markets where the neutral is not distributed as a protected pole — verify the panel's neutral bus arrangement before specifying. That's a wide range — fine for control-circuit tails (1.5 mm²) up to main feeder taps (10 mm² or 16 mm²). Touch protection is built into the terminal design (IP20 with connected conductors). Sealable terminals allow the panel builder to lock the cover screws after commissioning — useful for installations where tamper-proofing is required. ## Environmental range and lifecycle Designed for mechanical engineering and industrial applications per the manufacturer's suitability listing. The 5SY6 series is the standard industrial MCB line within the SENTRON portfolio, positioned between the domestic 5SL series and the high-performance 5SY7 range.","metaTitle":"Siemens 5SY6506-8 SENTRON MCB, 6A D-curve, 2-pole 1P+N, 30kA","metaDescription":"Siemens SENTRON 5SY6506-8 miniature circuit breaker, 6 A rated, D tripping characteristic, 2-pole 1P+N, 30 kA IEC 60947-2, 6 kA EN 60898.

The terminal range (0.75–35 mm²) is the same. The key difference is the tripping characteristic: 5SY6506-8 is D-curve (10–20× In), while 5SY4140-7 is a different curve — check the existing panel's coordination study before swapping."},{"question":"How do I get current pricing and availability for 5SY6506-8?","answer":"Sourced to order against an RFQ through independent distribution.
