| Design Of The Product | For motor protection |
Trip Class 10 gives you a 10-second maximum trip time at 7.2× rated current, which is the standard for standard-duty motor starts (pumps, fans, compressors).
The 45 mm width and 97 mm depth mean it fits standard DIN-rail enclosures without overhang — plan for 50 mm clearance above and below and 30 mm at the sides for airflow and wiring access. Spring-loaded terminals on the main circuit accept 2×(0.5–4 mm²) solid or stranded, so no lug crimping needed for motor leads up to 4 mm².
We supply it through independent distribution channels. Submit an RFQ for volume pricing and current availability — confirmed at quote time.
Both share the same 45 mm width and DIN-rail mounting, so the footprint matches. The -0JA20-ZX95 uses spring-loaded terminals; the -0BA20 may use screw terminals. Check your panel's terminal type before swapping — if it's wired for screw terminals, you may need to adapt the wiring method.
The depth is 97 mm, which fits standard DIN-rail enclosures without overhang.
The width is 45 mm, a standard single-module width for this class of motor protection breaker.
