⁄Ω¢∑ ≈ 1⁄Ω¢∑

5mm x 20mm

• All holder bodies have the option of

using either ⁄Ω¢∑ ≈ 1⁄Ω¢∑ or

5mm ≈ 20mm carriers.

• This feature allows the OEM the

flexibility of shipping equipment to

international destinations simply by

changing the fuse carriers.

• The HTB-20 and 30 series are low

profile versions minimizing front panel

exposure.

• The HTB-40 and 50 series are high

profile versions conserving critical,

behind-panel space.
