What is the difference between the J250S and the JD250S circuit breaker enclosures?
Clarifying product features differences
The JD250S is physically smaller than the J250S and has application limitations. The JD250S is UL listed only to accept a HDL or JDL, 3-Pole circuit breaker. The voltage is limited to 480Vac maximum. The SCCR is limited to 18K rms symmetrical amperes at 240Vac or 480Vac. Copper conductors must be used (aluminum conductors are not acceptable).
