- ※1 遮断可能な最大電圧値です。(抵抗部に印加される電圧ではありませんのでご注意下さい）電圧が60Vを超える場合は、軽減曲線に従って、負荷を軽減して下さい。
- ※使用温度が70℃を超える場合は軽減曲線に従って負荷を軽減して下さい。
- ※要求により，4.7Ω～160Ω(±5%)の間で，新タイプとして設定可能です。UL規格(UL1412)には定格電流の規定がなく、表中の定格電流は弊社独自の設定値です。

※FM5 is indentifying symbol of terminal specification.
※Please feel free to contact us in regard of M4 terminal.
※1 This is maximum voltage value at which BZ07 can open a circuit under rated current condition. (Please note it is different from voltage value that can be applied to resistor part.)Please use BZ07 in accordance with the derating curve, if voltage exceeds 60V.
※Please us BZ07 in accordance with the derating curve, if ambient temperature exceeds 70℃.
※Resistance value can be changed 4.7Ω～160Ω(±5%) as new type. UL1412 contains no provisions concerning rated current, so above-mentioned is our own specification.
