DESCRIPTION
New open box Ferraz Shawmut A070GRB16T13 Protistor high-speed semiconductor fuse, reference number J330012, rated 16 A at 700 VAC. The body is marked "Ferraz Shawmut, J330012, 660V ac 16A, 660 GRB 10-16, A070 gRB 16 T13," with Protistor, UL Recognized and semiconductor-fuse symbols. The fuse has not been installed. The ferrules show tarnish from storage, as pictured.

The A070GRB series is Ferraz Shawmut's 10 x 38 mm gR fuse. It is fast acting and current limiting, with low I²t, and protects rectifiers, thyristors, inverters, UPS systems, soft starters and other power semiconductors. Ferraz Shawmut is now Mersen, which still sells the part under the same catalog number.

Features:
16 A, 700 VAC (UL) / 660 VAC (IEC marked)
550 VDC rating (L/R = 10 ms)
160 kA AC interrupting rating
Extremely fast acting, current limiting, low I²t
gR full-range class for semiconductor protection
10 x 38 mm cylindrical ferrule, non-indicating
Ceramic body
UL Recognized (JFHR2), IEC 60269-4

Compatibility:
Direct replacement for Ferraz Shawmut or Mersen A070GRB16T13 (J330012). It fits standard 10 x 38 mm fuse clips and holders rated for the circuit voltage. Mersen's current 10 x 38 gR 16 A Protistor is FR10GR69V16; check its ratings against your equipment before substituting. Do not replace this fuse with a general-purpose gG or Class CC fuse in a semiconductor circuit, because they do not clear fast enough to protect drives and rectifiers.

Q&A
Q: What size is this fuse?
A: 10 x 38 mm (13/32 x 1-1/2 in), a cylindrical ferrule.
Q: What is J330012?
A: It is the Ferraz Shawmut/Mersen reference (item) number for the A070GRB16T13 and is printed on the fuse body.
Q: Why does the fuse say 660V when the listing says 700V?
A: The body carries the IEC marking of 660 VAC. Mersen's UL rating for the A070GRB series is 700 VAC.
Q: Can I use it on DC?
A: Yes. The series is rated 550 VDC with a time constant (L/R) of 10 ms.
Q: Is this a time-delay fuse?
A: No. It is an extremely fast-acting semiconductor fuse.

DISCLAIMER
Item is new open box, sold as pictured. The fuse has not been installed but shows tarnish from storage. Ships fast with tracking. 30-day returns accepted; buyer pays return shipping.
