5S Miniature Circuit Breakers
Siemens MCB portfolio offers reliable protection against short circuits and overload for applications in industry, buildings, and infrastructure
Siemens 5SJ miniature circuit breakers (MCBs) are UL listed to UL 489 and certified to Canadian standards CSA 22.2 No. 5.02. They are available with one, two, and three poles, 0.3 A to 63 A, and 240 VAC or 480Y/277 VAC voltage ranges. Accessories include UL listed auxiliary switches, fault signal contacts, and shunt trips.
In addition, Siemens 5SY and 5SP supplementary protectors are UL1077 recognized, certified to Canadian standards CSA 22.2 No. 235, and IEC/EN 60 947-2 EN 60 898. This line of protectors complies with global standards and comes with CE markings. They are available in one, two, and three pole configurations, ranging from 0.3 A to 125 A, and rated 277 VAC for 1-P and 480 VAC for multi-poles.
5SJ Features
- Trip curves of B (3 to 5 In), C (5 to 10 In), and D (10 to 20 In) to meet varying load characteristics
- Touch-safe design to ensure reliable personal safety against electric shock
- Visible indicator for ON and OFF/Trip indication; even changes if the trip handle is held in place
- DIN rail mounting (standard 35 mm) for easy installation without tools
- Use for circuits with rated currents from 0.3 A to 63 A
- Expandable with comprehensive accessories such as busbars and auxiliary switches, fault signal contacts, and shunt trips up to 480 V
5SJ Applications
- Branch circuit or feeder protection
- UL 489 devices in questionable UL 1077 (supplementary protection) applications
- Current ratings below 10 A
- Smaller size than traditional molded case circuit breakers or fuse blocks
5SY Features
- Designed for applications with rated currents from 0.3 A to 80 A
- Compact design, easy mounting, infeed optionally at either the top or bottom through identical terminals
- Industry-standard mounting with DIN rail compatibility
- With characteristics A, B, C, and D, diverse uses: from residential buildings with high inrush currents and pulse-generating equipment, down to protection of semiconductors
- Highly effective touch protection when grasping and mounting the latching slide with latch-down option
- Visible indicator for ON and OFF/Trip
- Identical wire screw connections on line and load side – with dual terminal for cable and busbar
5SY Applications
- Selectivity for multiple motor control circuits on the secondary side of a control transformer or power supply by allowing the user to quickly find the problem circuit should a fault occur without having to shut down all of the other control circuits
- Use as a local disconnecting means inside the panel when a branch circuit protection device is already present
- Applicable for protection of small devices, even below 10A
